2016 Honda Odyssey problems

“My 2016 Honda Odyssey has experienced repeated engine misfires associated with oil-fouled spark plugs. In May 2024, while driving, the check-engine light began flashing and the vehicle ran rough. An authorized Honda dealer inspected the vehicle and documented an oil-fouled spark plug. The dealer replaced all six spark plugs, but the underlying cause was not repaired. In November 2025, the check-engine light returned. An independent repair shop documented code P0303, Cylinder 3 Misfire, and replaced all six spark plugs again. In August 2026, the same problem returned. The repair shop again documented a Cylinder 3 misfire and found all three rear-bank spark plugs fouled. They recommended an internal engine inspection because repeated spark-plug replacement was not correcting the underlying problem. The vehicle was then taken to an authorized Honda dealer, which recommended an engine piston-ring/re-ring repair. The recurring misfire causes the vehicle to run rough and the check-engine light to flash, creating concern about loss of engine performance while driving. The vehicle and engine are available for inspection.”

“Odometer Fraud. The contact purchased a 2016 Honda Odyssey. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 142,069, and at the time of maintenance, it was discovered that the mileage was 197,779.”

“I am sending you information about how a situation was handled by Honda, so hopefully others do not go through the same problems we did. Honda customer service and product advisory is what failed us and we are grateful that we didn't have an accident. I am attaching my documentation below.”

“Under 45 degrees, the back door will not open. The latch is faulty and fails in moderate to severe cold weather. In an emergency where we would need to exit the rear of the vehicle, there’s no way to open the rear door from the inside or outside. It is under 45 degrees for about half the year where I live. It is more than just an inconvenience, it is a safety concern.”

“the problem only happens after driving for more than 30 minutes. when I stop at a light, the engine starts shaking and stalls. the starter seems cranking normally, but it takes about 3 attempts and about 40 seconds to restart. One day, the engine stopped while I was driving. There is no Check Engine Light. I took it to Honda dealer. but they keep saying they cannot replicate the problem. It is so dangerous to drive this car.”
